I　will　give　an　instance　of　the　extreme　disturbance　of　mind　to　which　some　sensitive　men　are　liable。　　A　gentleman；　on　whom　I　can　rely；　assured　me　that　he　had　been　an　eye…witness　of　the　following　scene：A　small　dinner…party　was　given　in　honour　of　an　extremely　shy　man；　who；　when　he　rose　to　return　thanks；　rehearsed　the　speech；　which　he　had　evidently　learnt　by　heart；　in　absolute　silence；　and　did　not　utter　a　single　word；　but　he　acted　as　if　he　were　speaking　with　much　emphasis。　His　friends；　perceiving　how　the　case　stood；　loudly　applauded　the　imaginary　bursts　of　eloquence；　whenever　his　gestures　indicated　a　pause；　and　the　man　never　discovered　that　he　had　remained　the　whole　time　completely　silent。　　On　the　contrary；　he　afterwards　remarked　to　my　friend；　with　much　satisfaction；　that　he　thought　he　had　succeeded　uncommonly　well。

When　a　person　is　much　ashamed　or　very　shy；　and　blushes　intensely；　his　heart　beats　rapidly　and　his　breathing　is　disturbed。　This　can　hardly　fail　to　affect　the　circulation　of　the　blood　within　the　brain；　and　perhaps　the　mental　powers。　It　seems　however　doubtful；　judging　from　the　still　more　powerful　influence　of　anger　and　fear　on　the　circulation；　whether　we　can　thus　satisfactorily　account　for　the　confused　state　of　mind　in　persons　whilst　blushing　intensely。

The　true　explanation　apparently　lies　in　the　intimate　sympathy　which　exists　between　the　capillary　circulation　of　the　surface　of　the　head　and　face；　and　that　of　the　brain。　On　applying　to　Dr。　J。　Crichton　Browne　for　information；　he　has　given　me　various　facts　bearing　on　this　subject。　When　the　sympathetic　nerve　is　divided　on　one　side　of　the　head；　the　capillaries　on　this　side　are　relaxed　and　become　filled　with　blood；　causing　the　skin　to　redden　and　to　grow　hot；　and　at　the　same　time　the　temperature　within　the　cranium　on　the　same　side　rises。　　Inflammation　of　the　membranes　of　the　brain　leads　to　the　engorgement　of　the　face；　ears；　and　eyes　with　blood。　The　first　stage　of　an　epileptic　fit　appears　to　be　the　contraction　of　the　vessels　of　the　brain；　and　the　first　outward　manifestation　is；　an　extreme　pallor　of　countenance。　　Erysipelas　of　the　head　commonly　induces　delirium。　　Even　the　relief　given　to　a　severe　headache　by　burning　the　skin　with　strong　lotion；　depends；　I　presume；　on　the　same　principle。

Dr。　Browne　has　often　administered　to　his　patients　the　vapour　of　the　nitrite　of　amyl；＇22＇　which　has　the　singular　property　of　causing　vivid　redness　of　the　face　in　from　thirty　to　sixty　seconds。　This　flushing　resembles　blushing　in　almost　every　detail：　it　begins　at　several　distinct　points　on　the　face；　and　spreads　till　it　involves　the　whole　surface　of　the　head；　neck；　and　front　of　the　chest；　but　has　been　observed　to　extend　only　in　one　case　to　the　abdomen。　The　arteries　in　the　retina　become　enlarged；　the　eyes　glisten；　and　in　one　instance　there　was　a　slight　effusion　of　tears。　The　patients　are　at　first　pleasantly　stimulated；　but；　as　the　flushing　increases；　they　become　confused　and　bewildered。　One　woman　to　whom　the　vapour　had　often　been　administered　asserted　that；　as　soon　as　she　grew　hot；　she　grew　MUDDLED。　　With　persons　just　commencing　to　blush　it　appears；　judging　from　their　bright　eyes　and　lively　behaviour；　that　their　mental　powers　are　somewhat　stimulated。　It　is　only　when　the　blushing　is　excessive　that　the　mind　grows　confused。　Therefore　it　would　seem　that　the　capillaries　of　the　face　are　affected；　both　during　the　inhalation　of　the　nitrite　of　amyl　and　during　blushing；　before　that　part　of　the　brain　is　affected　on　which　the　mental　powers　depend。

Conversely　when　the　brain　is　primarily　affected；　the　circulation　of　the　skin　is　so　in　a　secondary　manner。　Dr。　Browne　has　frequently　observed；　as　he　informs　me；　scattered　red　blotches　and　mottlings　on　the　chests　of　epileptic　patients。　In　these　cases；　when　the　skin　on　the　thorax　or　abdomen　is　gently　rubbed　with　a　pencil　or　other　object；　or；　in　strongly…marked　cases；　is　merely　touched　by　the　finger；　the　surface　becomes　suffused　in　less　than　half　a　minute　with　bright　red　marks；　which　spread　to　some　distance　on　each　side　of　the　touched　point；　and　persist　for　several　minutes。　　These　are　the　_cerebral　maculae_　of　Trousseau；　and　they　indicate；　as　Dr。　Browne　remarks；　a　highly　modified　condition　of　the　cutaneous　vascular　system。　If；　then；　there　exists；　as　cannot　be　doubted；　an　intimate　sympathy　between　the　capillary　circulation　in　that　part　of　the　brain　on　which　our　mental　powers　depend；　and　in　the　skin　of　the　face；　it　is　not　surprising　that　the　moral　causes　which　induce　intense　blushing　should　likewise　induce；　independently　of　their　own　disturbing　influence；　much　confusion　of　mind。

_The　Nature　of　the　Mental　States　which　induce　Blushing_。These　consist　of　shyness；　shame；　and　modesty；　the　essential　element　in　all　being　self…attention。　Many　reasons　can　be　assigned　for　believing　that　originally　self…attention　directed　to　personal　appearance；　in　relation　to　the　opinion　of　others；　was　the　exciting　cause；　the　same　effect　being　subsequently　produced；　through　the　force　of　association；　by　self…attention　in　relation　to　moral　conduct。　It　is　not　the　simple　act　of　reflecting　on　our　own　appearance；　but　the　thinking　what　others　think　of　us；　which　excites　a　blush。　In　absolute　solitude　the　most　sensitive　person　would　be　quite　indifferent　about　his　appearance。　　We　feel　blame　or　disapprobation　more　acutely　than　approbation；　and　consequently　depreciatory　remarks　or　ridicule；　whether　of　our　appearance　or　conduct；　causes　us　to　blush　much　more　readily　than　does　praise。　But　undoubtedly　praise　and　admiration　are　highly　efficient：　a　pretty　girl　blushes　when　a　man　gazes　intently　at　her；　though　she　may　know　perfectly　well　that　he　is　not　depreciating　her。　Many　children；　as　well　as　old　and　sensitive　persons　blush；　when　they　are　much　praised。　　Hereafter　the　question　will　be　discussed；　how　it　has　arisen　that　the　consciousness　that　others　are　attending　to　our　personal　appearance　should　have　led　to　the　capillaries；　especially　those　of　the　face；　instantly　becoming　filled　with　blood。

My　reasons　for　believing　that　attention　directed　to　personal　appearance；　and　not　to　moral　conduct；　has　been　the　fundamental　element　in　the　acquirement　of　the　habit　of　blushing；　will　now　be　given。　They　are　separately　light；　but　combined　possess；　as　it　appears　to　me；　considerable　weight。　　It　is　notorious　that　nothing　makes　a　shy　person　blush　so　much　as　any　remark；　however　slight；　on　his　personal　appearance。　　One　cannot　notice　even　the　dress　of　a　woman　much　given　to　blushing；　wihout　causing　her　face　to　crimson。　It　is　sufficient　to　stare　hard　at　some　persons　to　make　them；　as　Coleridge　remarks；　blush；〃account　for　that　he　who　can。〃＇23＇

It　is　plain　to　every　one　that　young　men　and　women　are　highly　sensitive　to　the　opinion　of　each　other　with　reference　to　their　personal　appearance；　and　they　blush　incomparably　more　in　the　presence　of　the　opposite　sex　than　in　that　of　their　own。＇25＇　A　young　man；　not　very　liable　to　blush；　will　blush　intensely　at　any　slight　ridicule　of　his　appearance　from　a　girl　whose　judgment　on　any　important　subject　lie　would　disregard。　No　happy　pair　of　young　lovers；　valuing　each　other's　admiration　and　love　more　than　anything　else　in　the　world；　probably　ever　courted　each　other　without　many　a　blush。　　Even　the　barbarians　of　Tierra　del　Fuego；　according　to　Mr。　Bridges；　blush　〃chiefly　in　regard　to　women；　but　certainly　also　at　their　own　personal　appearance。〃
